wip(ssr): further restructure

fix(runtime-core): render context set should not unwrap reactive values

wip(ssr): restructure

release: v3.0.0-alpha.4

chore: add compiler-ssr to skipped packages for now

refactor: remove implicit reactive() call on renderContext

reference: https://github.com/vuejs/rfcs/issues/121

BREAKING CHANGE: object returned from `setup()` are no longer implicitly
passed to `reactive()`.

  The renderContext is the object returned by `setup()` (or a new object
  if no setup() is present). Before this change, it was implicitly passed
  to `reactive()` for ref unwrapping. But this has the side effect of
  unnecessary deep reactive conversion on properties that should not be
  made reactive (e.g. computed return values and injected non-reactive
  objects), and can lead to performance issues.

  This change removes the `reactive()` call and instead performs a
  shallow ref unwrapping at the render proxy level. The breaking part is
  when the user returns an object with a plain property from `setup()`,
  e.g. `return { count: 0 }`, this property will no longer trigger
  updates when mutated by a in-template event handler. Instead, explicit
  refs are required.

  This also means that any objects not explicitly made reactive in
  `setup()` will remain non-reactive. This can be desirable when
  exposing heavy external stateful objects on `this`.

wip(ssr): revert reactivity ssr paths

The perf gains are not worth the correctness issues these paths may lead to

test: update snapshots for toDisplayString

fix(runtime-core): instance should not expose non-declared props

refactor: better variable naming

wip(ssr): escape helpers

chore: fix ssr compiler version

perf(ssr): avoid unnecessary async overhead

test: fix dts tests for 1ccecc0

wip(ssr): reduce reactivity overhead during ssr

wip(ssr): render real components

wip(ssr): initial work on server-renderer

refactor: adjust `createApp` related API signatures

BREAKING CHANGE: `createApp` API has been adjusted.

  - `createApp()` now accepts the root component, and optionally a props
  object to pass to the root component.
  - `app.mount()` now accepts a single argument (the root container)
  - `app.unmount()` no longer requires arguments.

  New behavior looks like the following:

  ``` js
  const app = createApp(RootComponent)
  app.mount('#app')
  app.unmount()
  ```

chore: scaffold ssr compiler
